DETAILED DESCRIPTION OF NON-LIMITING EXEMPLARY EMBODIMENTS 1. Embodiment 1-1. Configuration 1-1-1. Configuration of Information-Processing System 1

FIG. 1 is a diagram showing an example of a configuration of information-processing system 1 according to an embodiment. Information-processing system 1 includes game devices 10A and 10B, which will hereinafter be referred to as “game device 10” except where it is necessary to specify otherwise, and friend management server 20. It is of note that game devices 10A and 10B are examples of game device 10; three or more game devices 10 may be included in information-processing system 1. Game devices 10 and friend management server 20 are connected with each other via network 30, which is the Internet.

1-1-2. Configuration of Game Device 10

Game device 10 is an example of an information-processing device, and is, specifically, a portable computer game device. It is of note that in a modification, game device 10 may be a stationary computer game device. FIG. 2 is a diagram showing an example of a configuration of game device 10. Game device 10 includes control unit 11, storage unit 12, display unit 13, operation input unit 14, network communication unit 15, and local communication unit 16. It is of note that in a modification, storage unit 12 may be an external storage medium.

Control unit 11 includes a processor such as a CPU or a GPU, and a volatile memory, which unit executes programs stored in storage unit 12. Functions provided by control unit 11 will be described later.

Storage unit 12 is a storage device such as a flash memory, which unit stores programs to be executed by control unit 11, which programs include a friend registration program for enabling friend registration and a variety of game programs. A friendship herein refers to a relationship established based on a mutual agreement between users. A friendship is established under a condition that a user sends a friend request to another user to request establishment of a friendship, and the other user approves the friend request. It is of note that in a modification, a friendship may be established under a condition that users exchange friend requests.

Methods for requesting establishment of a friendship include a method using local communication, a method using a multi-play function, and a method using a friend code. In the method using local communication, a user causes his/her game device 10 to acquire a user ID of another user from game device 10 of the other user, using local communication, based on which user ID, establishment of a friendship is requested. The local communication performed herein is responsive to a user's input operation, and is dedicated to requesting establishment of a friendship.

In the method using a multi-play function, a user causes his/her game device 10 to acquire a user ID of another user so that the user can play a game with the other user, based on which user ID, establishment of a friendship is requested. Multi-play methods include a method using local communication and a method using Internet communication. Detailed information on multi-play methods is described in, for example, Japanese Unexamined Patent Application Publication No. 26-334386. The method using a multi-play function is, more specifically, divided into a method by which establishment of a friendship is requested during a game play, and a method by which establishment of a friendship is requested after a game play based on a game play history. The latter method will be described later.

In the method using a friend code, a user inputs a friend code of another user in his/her game device 10, based on which friend code establishment of a friendship is requested.

Users who have become friends are able to share information with each other. For example, among users who have become friends using a social networking service (SNS) application, a user can automatically acquire a message posted by another user, or know whether the other user is logged in. Also, users who have become friends are able to enjoy a game simultaneously. For example, the users are able to enjoy battle play or collaborative play together, or to be listed with an identical, joint ranking.

A game herein refers to a computer game such as an action game, a role playing game, or a puzzle game. A game includes a single player game that is played online or offline, and a multi-player game that is played using local communication or Internet communication. It is of note that a game includes an application for learning.

Storage unit 12 also stores identification information of a user of game device 10, which information includes, specifically, a user ID, a user name, a user image, and a friend code. The user ID is identification information uniquely assigned to the user in information-processing system 1, which information is, for example, an alphanumeric identification number. The user name is a character string representing a user's name such as a nickname, which character string is set by the user for general use in information-processing system 1. The user image is an image showing an appearance of the user, such as an avatar, which image is set by the user for general use in information-processing system 1. The friend code is identification information such as a twelve-digit identification number, uniquely assigned to the user information-processing system 1, which identification information is different from the user ID. The friend code is used only for friend registration.

Storage unit 12 also stores game history database (DB) 121 and multi-play history DB 122. FIG. 3 is a diagram showing an example of game history DB 121, which is a database for recording a history of games that the user of game device 10 has played using the game device. Any type of game, whether a multi-player game or a single player game, or whether an online play game or an offline play game, may be recorded in game history DB 121. Game history DB 121 records a game ID (ApplicationID), which is identification information of a game, and a play date and time in association with each other. Game history data recorded in game history DB 121 is uploaded to friend management server 20, together with the user ID, at a predetermined timing such as at the start of connection to friend management server 20, so that the uploaded data is recorded in game history DB 224 (described later).

FIG. 4 is a diagram showing an example of multi-play history DB 122, which is a database for recording a history of multi-play sessions that the user of game device 10 has performed together with a user(s) of one or more game devices 10. Any type of multi-play session, regardless of a communication method (a local multi-play session or an Internet multi-play session), may be recorded in multi-play history DB 122. Multi-play history DB 122 records a user ID and an in-game user name of another user, a game ID, a play date and time, a communication method, and an in-game user name of the user in association with each other. An in-game user name herein refers to a character string representing a user's name such as a nickname, which character string is set by the user for use in a particular game. An in-game user name may or may not be identical to a user name generally used in information-processing system 1. It is of note that in a modification, an in-game user name may be replaced with an in-game user image as identification information for use in a particular game. Information on a multi-play session is recorded in multi-play history DB 122, each time a multi-play session is performed. When a multi-play session with an identical user is performed plural times, information on the latest multi-play session is retained in multi-play history DB 122.

Now, display unit 13 is a display device such as a liquid crystal display or an organic electroluminescence (EL) display.

1-2. Operation

An operation carried out in information-processing system 1 to register a friend will be described. Specifically, as an example, an operation to register a friend using a multi-play history will be described, which operation is based on an assumption that that user A of game device 10A sends a friend request to user B of game device 10B. FIGS. 11 and 12 are sequence diagrams showing an example of the present operation.

When user A of game device 10A performs an input operation using operation input unit 14 to cause a multi-play history list screen to be displayed, multi-play information acquiring unit 1104 of the game device sends a multi-play information request to friend management server 20 (step S1). On accepting the multi-play information request, multi-play information sending unit 211 of friend management server 20 generates multi-play information by referring to user information DB 221, game history DB 224, and game information DB 225 to send the generated multi-play information to game device 10A (step S2).

When the multi-play information is acquired by multi-play information acquiring unit 1104 of game device 10A, screen generating unit 1110 of the game device generates a multi-play history list screen by referring to the acquired multi-play information and multi-play history DB 122. After the multi-play history list screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S3). FIG. 13 is a diagram showing an example of the multi-play history list screen.

The multi-play history list screen is a screen capable of showing identification information of other users with which user A of game device 10A has played a game using near field communication, and identification information of other users with which user A has played a game using Internet communication. The screen is displayed to enable user A to send a friend request to another user with whom user A has played a game. Also, the screen is displayed to enable user A to prevent establishment of a friendship with another user with whom user A has played a game, and to cancel an established friendship.

In the multi-play history list screen, items of identification information of other users are arranged on a play date and time basis in chronological order, regardless of a communication method (local communication or Internet communication) used for a multi-play session. In the example screen shown in FIG. 13, identification information of another user with whom the user has played recently is shown at the upper left side. Each of the items of identification information of other users includes user image 31 and user name 32, in association with which identification information, play date and time 33 and game name 34 are shown.

When user A, in the multi-play history list screen, performs an input operation using operation input unit 14, in response to which selecting unit 1112 selects user image 31 of user B, screen generating unit 1110 generates a detailed screen of user B by referring to the multi-play information acquired at step S2 and multi-play history DB 122. After the detailed screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S4). FIG. 14 is a diagram showing an example of the detailed screen of user B.

The detailed screen of user B includes identification information of user B, identification information and play date and time 46 of a game that user A has played with user B, a game history of user B, friend request button B1, and block button B2. The identification information of user B includes user image 41, user name 42, and in-game user name 43 of user B. The identification information of a game that user A has played with user B includes game name 44 and game image 45. The game history of user B includes one or more sets of game name 47, game image 48, and play date and time 49, in which game history, items of information on a game are arranged on a play date and time basis in chronological order. In the example screen shown in FIG. 14, information on a game played recently is shown at the top. When user A, in the detailed screen, selects block button B2 using operation input unit 14, a user ID of user B is registered in a block list (not shown) so that an oncoming friend request from user B is not displayed on display unit 13. On the other hand, when user A selects friend request button B1, friend request sending unit 1105 of game device 10A generates a friend request by referring to multi-play history DB 122, in which friend request a user ID and an in-game user name of user A, who is a sender of the request, a user ID and an in-game user name of user B, who is a receiver of the request, a channel type, and a game ID are specified. In the present example operation, a channel type “multi-play” is specified. After generating the friend request, friend request sending unit 1105 sends the generated friend request to friend management server 20 (step S5).

It is of note that in a modification, the detailed screen of user B may include a button for requesting a multi-play session (rematch) with user B, selection of which button causes first communication game unit 1102 or second communication game unit 1103 to enable user A to play a game with user B. In such a case, the multi-play history list screen is displayed to enable user A to play a game with user B.

When the friend request sent from game device 10A is accepted by friend request accepting unit 212 of friend management server 20, the friend request accepting unit registers information on the accepted friend request in friend request information DB 222 (step S6). Specifically, friend request accepting unit 212 records, in friend request information DB 222, the user ID and the in-game user name of user A, who is the sender of the friend request, the user ID and the in-game user name of user B, who is the receiver of the friend request, a date and time of acceptance (request date and time), the channel type, and the game ID.

After step S6, when user A of game device 10A, who is the sender of the friend request, performs an input operation using operation input unit 14 to cause a sent-request list screen to be displayed, sent-request information acquiring unit 1107 of the game device sends a sent-request information request to friend management server 20 (step S7). On receiving the sent-request information request, sent-request information sending unit 214 of friend management server 20 generates sent-request information by referring to friend request information DB 222, user information DB 221, game history DB 224, and game information DB 225 to send the generated sent-request information to game device 10A (step S8).

When the sent-request information is acquired by sent-request information acquiring unit 1107 of game device 10A, screen generating unit 1110 of the game device generates a sent-request list screen based on the acquired sent-request information. After the sent-request list screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S9). FIG. 15 is a diagram showing an example of the sent-request list screen.

The sent-request list screen is a screen showing a list of one or more friend requests which user A has sent to other users, in which list, the friend requests are arranged on a request date and time basis in chronological order. In the example screen shown in FIG. 15, friend requests are arranged such that those having a later request date and time are shown at the top. In display area 51 of each of the friend requests, user image 52 and user name 53 of a receiver of a friend request, and game name 54 indicative of a request method are shown in association with each other. It is of note that in a modification, a game image or an in-game user name of a receiver of a friend request may be shown in addition to or instead of a game name.

When user A, in the sent-request list screen, selects the friend request sent to user B, using operation input unit 14, screen generating unit 1110 generates a detailed screen of the selected friend request based on the sent-request information acquired from friend management server 20. After the detailed screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S10). FIG. 16 is a diagram showing an example of the detailed screen of the friend request sent to user B, which screen can be displayed after user A sends the friend request to user B.

The detailed screen of the friend request is a screen showing identification information of user B, who is the receiver of the friend request, and a request method by which establishment of a friendship with user B has been requested by user A. The identification information of user B includes user image 61 and user name 62 of user B. Information indicative of the request method includes game name 63, game image 64, and in-game user name 65 of user B, display of which items of information indicates that the friend request has been triggered by a multi-play session. The detailed screen of the friend request also includes a history of games played by user B, which history includes one or more sets of game name 66, game image 67, and play date and time 68, which sets of information are arranged on a play date and time basis in chronological order. In the example screen shown in FIG. 16, sets of information are arranged such that those having a later play date and time are shown at the top. The detailed screen of the friend request also includes request date and time 69 and cancel button B3. When user A, in the detailed screen, selects cancel button B3 using operation input unit 14, game device 10A sends a request to cancel the friend request to friend management server 20. On the other hand, when user A performs an input operation to cause the previous screen to be displayed, display control unit 1111 again causes display unit 13 to display the sent-request list screen.

On the other hand, after step S6, when user B of game device 10B, who is the receiver of the friend request, performs an input operation using operation input unit 14 to cause a received-request list screen to be displayed, received-request information acquiring unit 1106 of the game device sends a received-request information request to friend management server 20 (step S11). On receiving the received-request information request, received-request information sending unit 213 of friend management server 20 generates received-request information by referring to friend request information DB 222, user information DB 221, game history DB 224, and game information DB 225 to send the generated received-request information to game device 10B (step S12).

When the received-request information is acquired by received-request information acquiring unit 1106 of game device 10B, screen generating unit 1110 of the game device generates a received-request list screen based on the acquired received-request information. After the received-request list screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S13). FIG. 17 is a diagram showing an example of the received-request list screen.

The received-request list screen is a screen showing a list of one or more friend requests that user B has received from other users, in which list the friend requests are arranged on a request date and time basis in chronological order. In the example screen shown in FIG. 17, friend requests are arranged such that those having a later request date and time are shown at the top. In display area 71 of each of the friend requests, user image 72 and user name 73 of a sender of a friend request, and game name 74 indicative of a request method are shown in association with each other. It is of note that in a modification, a game image or an in-game user name of a sender of a friend request may be shown in addition to or instead of a game name.

When user B, in the received-request list screen, selects the friend request sent from user A, using operation input unit 14, screen generating unit 1110 generates a detailed screen of the selected friend request based on the received-request information acquired from friend management server 20. After the detailed screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S14). FIG. 18 is a diagram showing an example of the detailed screen of the friend request sent from user A, which screen can be displayed after user A sends the friend request to user B.

The detailed screen of the friend request is a screen showing identification information of user A, who is the sender of the friend request, and a request method by which establishment of a friendship with user B has been requested by user A. The identification information of user A includes user image 81 and user name 82 of user A. Information indicative of the request method includes game name 83, game image 84, and in-game user name 85 of user A, display of which items of information indicates that the friend request has been triggered by a multi-play session, which information is useful for user B in deciding whether to approve the friend request. The detailed screen of the friend request also includes a history of games played by user A, which is also useful for user B in deciding whether to approve the friend request. The history of games includes one or more sets of game name 86, game image 87, and play date and time 88, which sets of information are arranged on a play date and time basis in chronological order. In the example screen shown in FIG. 18, sets of information are arranged such that those having a later play date and time are shown at the top. The detailed screen of the friend request also includes request date and time 89, request approve button B4, delete button B5, and block button B6. When user B, in the detailed screen, selects delete button B5 using operation input unit 14, response sending unit 1108 of game device 10B sends a response indicative of an intention to reject the friend request from user A to friend management server 20. When user B selects block button B2, a user ID of user A is registered in a block list (not shown) so that an oncoming friend request from user A is not displayed on display unit 13. When user B selects request approve button B4, response sending unit 1108 sends a response indicative of an intention to approve the friend request from user A to friend management server 20 (step S15).

When the response is accepted by response accepting unit 215 of friend management server 20, the response accepting unit registers user A as a friend of user B (step S16). Specifically, response accepting unit 215, by referring to friend request information DB 222, registers identification information of user A and a request method (in other words, friend establishing method) in friend information DB 223 in association with the user ID of user B. More specifically, response accepting unit 215 registers the user ID and the in-game user name of user A, a response-accepted date and time (friend-established date and time), a channel type, and a game ID. Also, response accepting unit 215, by referring to friend request information DB 222, registers identification information of user B and a request method (in other words, friend establishing method) in friend information DB 223 in association with the user ID of user A. Specifically, response accepting unit 215 registers the user ID and the in-game user name of user B, a response-accepted date and time (friendship-established date and time), a channel type, and a game ID. After completing the friend registration, response accepting unit 215 sends a friend registration completion notice to game devices 10A and 10B (steps S17 and S18).

After the friend registration is completed, when user B of game device 10B, who is the receiver of the friend request, performs an input operation using operation input unit 14 to cause a friend list screen to be displayed, friend information acquiring unit 1109 of the game device sends a friend information request to friend management server 20 (step S19). On receiving the friend information request, friend information sending unit 216 of friend management server 20 generates friend information by referring to friend information DB 223, user information DB 221, game history DB 224, and game information DB 225 to send the generated friend information to game device 10B (step S20).

When the friend information is acquired by friend information acquiring unit 1109 of game device 10B, screen generating unit 1110 of the game device generates a friend list screen based on the acquired friend information. After the friend list screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S21). FIG. 19 is a diagram showing an example of the friend list screen.

The friend list screen is a screen showing a list of other users who are friends of user B, in which list the other friends are arranged on a friendship-established date and time basis in chronological order. In the example screen shown in FIG. 19, other users are arranged such that those having a later friendship-established date and time are shown at the top. In display area 91 of each of the other users, user image 92 and user name 93 of another user are shown. It is of note that in a modification, a friendship establishing method may be shown in association with user image 92 and user name 93 of another user. It is also of note that in another modification, online users may be shown above offline users.

When user B, in the friend list screen, selects user A using operation input unit 14, screen generating unit 1110 generates a detailed screen of user A based on the friend information acquired from friend management server 20. After the detailed screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S22). FIG. 20 is a diagram showing an example of the detailed screen of user A, which screen can be displayed after user A and user B have established a friendship.

The detailed screen of user A is a screen showing identification information of user A, who is a friend of user B, and a friendship-establishing method by which a friendship has been established between user A and user B, in which screen a friendship-establishing method is shown instead of a request method. The identification information of user A includes user image 101 and user name 102 of user A. Information indicative of the friendship-establishing method includes game name 103, game image 104, and in-game user name 105 of user A, display of which items of information indicates that establishment of a friendship has been triggered by a multi-play session. The detailed screen of user A also includes a history of games played by user A, which history includes one or more sets of game name 106, game image 107, and play date and time 108, which sets of information are arranged on a play date and time basis in chronological order. In the example screen shown in FIG. 20, sets of information are arranged such that those having a later play date and time are shown at the top. The detailed screen of user A also includes friendship-established request date and time 109. When user B, in the detailed screen, performs an input operation using operation input unit 14 to cause the previous screen to be displayed, display control unit 1111 again causes display unit 13 to display the friend list screen.

After the friend registration is completed, when user A of game device 10A, who is the sender of the friend request, performs an input operation using operation input unit 14 to cause a friend list screen to be displayed, friend information acquiring unit 1109 of the game device sends a friend information request to friend management server 20 (step S23). On receiving the friend information request, friend information sending unit 216 of friend management server 20 generates friend information by referring to friend information DB 223, user information DB 221, game history DB 224, and game information DB 225 to send the generated friend information to game device 10A (step S24).

When the friend information is acquired by friend information acquiring unit 1109 of game device 10A, screen generating unit 1110 of the game device generates a friend list screen based on the acquired friend information. After the friend list screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S25). FIG. 21 is a diagram showing an example of the friend list screen.

The friend list screen is a screen showing a list of other users who are friends of user A, in which list the other friends are arranged on a friendship-established date and time basis in chronological order. In the example screen shown in FIG. 21, other users are arranged such that those having a later friendship-established date and time are shown at the top. In display area 201 of each of the other users, user image 202 and user name 203 of another user are shown. It is of note that in a modification, a friendship establishing method may be shown in association with user image 202 and user name 203 of another user. It is also of note that in another modification, online users may be shown above offline users.

When user A, in the friend list screen, selects user B using operation input unit 14, screen generating unit 1110 generates a detailed screen of user B based on the friend information acquired from friend management server 20. After the detailed screen is generated, display control unit 1111 causes display unit 13 to display the generated screen (step S26). FIG. 22 is a diagram showing an example of the detailed screen of user B, which screen can be displayed after user A and user B have established a friendship.

The detailed screen of user B is a screen showing identification information of user B, who is a friend of user A, and a friendship-establishing method by which a friendship has been established between user A and user B, in which screen a friendship-establishing method is shown instead of a request method. The identification information of user B includes user image 301 and user name 302 of user B. Information indicative of the friendship-establishing method includes game name 303, game image 304, and in-game user name 305 of user B, display of which items of information indicates that establishment of a friendship has been triggered by a multi-play session. The detailed screen of user B also includes a history of games played by user B, which history includes one or more sets of game name 306, game image 307, and play date and time 308, which sets of information are arranged on a play date and time basis in chronological order. In the example screen shown in FIG. 22, sets of information are arranged such that those having a later play date and time are shown at the top. The detailed screen of user B also includes friendship-established request date and time 309. When user A, in the detailed screen, performs an input operation using operation input unit 14 to cause the previous screen to be displayed, display control unit 1111 again causes display unit 13 to display the friend list screen.

The foregoing is a description of the operation to register a friend.

According to information-processing system 1 described in the foregoing, a request method of a friend request is shown in a list of friend requests (see FIGS. 15 and 17) and a detailed screen (see FIGS. 16 and 18) of one of the friend requests; accordingly, a user of game device 10 is able to confirm a request method of a friend request that the user has sent or received. Also, a friendship-establishing method is shown in a detailed screen (see FIGS. 20 and 22) of a friend list; accordingly, a user of game device 10 is able to confirm a friendship-establishing method of his/her friend.

In contrast to the above exemplary operation, which enables friend registration using a multi-play history, in an operation that enables friend registration using local communication, a detailed screen (see FIGS. 16 and 18) of a list of friend requests shows, instead of a game name, a game image, and an in-game user name; for example, a message “Establishment of friendship requested using local communication” to indicate a request method. A detailed screen (see FIGS. 20 and 22) of a friend list shows, instead of a game name, a game image, and an in-game user name; for example, a message “Friendship established using local communication” to indicate a friendship-establishing method. In another operation that enables friend registration using a friend code, a detailed screen (see FIGS. 16 and 18) of a list of friend requests shows, instead of a game name, a game image, and an in-game user name; for example, a message “Establishment of friendship requested using friend code” to indicate a request method. A detailed screen (see FIGS. 20 and 22) of a friend list shows, instead of a game name, a game image, and an in-game user name; for example, a message “Friendship established using friend code” to indicate a friendship-establishing method. In another operation that enables friend registration during a game play, a request method and a friendship-establishing method are shown in the same manner as in the above exemplary operation that enables friend registration using a multi-play history.

2. Modifications

The above embodiment may be modified as described below. It is of note that two or more modifications described below may be combined with each other.

2-1. Modification 1

The friend registration program executed in game device 10 may be executed in an information-processing device such as a smartphone, a tablet device, or a wearable device.

Similarly, functions of friend management server 20 may be provided by information-processing devices connected by a communication line (in other words, an information-processing system).

2-2. Modification 2

In the multi-play history list screen shown in FIG. 13, a communication method used for a multi-play session may be shown in association with another user's identification information, which communication method may be made identifiable based on, for example, text, or a color, size, or position of user identification information.

2-3. Modification 3

In the multi-play history list screen shown in FIG. 13, items of another user's identification information may be arranged on the basis of a communication method used for a multi-play session; in other words, items of other users' identification information sharing a communication method may be grouped together and shown. Such an arrangement may be performed in response to a user's input operation after items of other users' identification information have been arranged in chronological order.

2-4. Modification 4

After the multi-play history list screen shown in FIG. 13 is displayed, display control unit 1111, in response to a user's selection of a communication method, may cause display unit 13 to display another screen showing only items of identification information of other users, who have performed a multi-play session using the selected communication method. In essence, display control unit 1111 may cause display unit 13 to display items of other users' identification information that have been selected on a communication method basis.

2-5. Modification 5

In the detailed screen of user B shown in FIG. 14, in a case where user A and user B have played plural games together, game names, game images, and in-game user names of the plural games may be shown. To enable plural games to be displayed, when user A and user B have played a game together plural times, old entries of multi-play sessions are not deleted from multi-play history DB 122 of game device 10.

2-6. Modification 6

Game device 10 may be shared by users. To enable this, plural accounts may be set up in game device 10. In that case, storage unit 12 stores multi-play history DB 122 for each of the plural accounts (in other words, user IDs).

2-7. Modification 7

In the list of friend requests shown in FIG. 15 or 17, friend requests may be arranged on a request method (specifically, channel type) basis; in other words, friend requests among which a request method is shared may be grouped together and shown. Such an arrangement may be performed in response to a user's input operation after friend requests have been arranged in chronological order. Similarly, in the friend list shown in FIG. 19 or 21, other users, who are friends, may be arranged on a friendship-establishing method (specifically, channel type) basis.

2-8. Modification 8

After the list of friend requests shown in FIG. 15 or 17 is displayed, display control unit 1111, in response to a user's selection of a request method (specifically, channel type), may cause display unit 13 to display another screen showing only friend requests that have been made using the selected request method. In essence, display control unit 1111 may cause display unit 13 to display friend requests that have been selected on a request method basis. Similarly, after the friend list shown in FIG. 19 or 21 is displayed, display control unit 1111, in response to a user's selection of a friendship-establishing method (specifically, channel type), may cause display unit 13 to display another screen showing only friends, a friendship with whom has been established using the selected friendship-establishing method.

2-9. Modification 9

In the detailed screen of a friend request list shown in FIG. 16 or 18, a request method may be shown in a manner such that a viewer can identify a sender or receiver of a friend request. For example, in the detailed screen shown in FIG. 16, a message “Friend request to user with whom you played together” may be shown to indicate a request method. In the detailed screen shown in FIG. 18, a message “Friend request from user with whom you played together” may be shown to indicate a request method. Similarly, in the detailed screen of a friend list shown in FIG. 20 or 22, a friendship-establishing method may be shown in a manner such that a viewer can identify a sender or receiver of a friend request. For example, in the detailed screen shown in FIG. 20, a message “Friendship established based on friend request from user with whom you played together” may be shown to indicate a friendship-establishing method. In the detailed screen shown in FIG. 22, a message “Friendship established based on friend request to user with whom you played together” may be shown to indicate a friendship-establishing method.

2-10. Modification 10

In the detailed screen of a friend request list shown in FIG. 16 or 18, two or more request methods may be shown. Specifically, in a case where establishment of a friendship has been requested using local communication, and a user ID of a receiver of the friend request is registered in multi-play history DB 122, not only a message “Friend request sent using local communication” but also a game name, a game image, and an in-game user name of a game played with the receiver may be shown to indicate a request method. In that case, two or more friendship-establishing methods may be shown in the detailed screen of a friend list shown in FIG. 20 or 22.

2-11. Modification 11

In the detailed screen of a friend request list shown in FIG. 18, not only a game name and a play date and time but also a length of play time and the number of sessions may be shown to indicate a game history. To enable such a display, game history DB 121 of game device 10 and game history DB 224 of friend management server 20 are configured to record lengths of play time. Similarly, in the detailed screen of a friend list shown in FIG. 20 or 22, a length of play time and the number of sessions may be shown.

2-12. Modification 12

In the detailed screen of a friend request list shown in FIG. 16, in a case where a sender of a friend request is a friend of another user, who is a friend of a receiver of the friend request, identification information of the other user may be shown. To enable such a display, friend management server 20 that has received a friend request and identified a friend common to a sender and a receiver of the received friend request, by referring to friend information DB 223, may include identification information of the identified friend in sent-request information so that the identification information may be shown in the detailed screen shown in FIG. 16. Alternatively, a sender of a friend request, who has selected a receiver from a friend list of his/her friend, may include identification information of the friend in the friend request sent to friend management server 20, and the friend management server may include the identification information in sent-request information so that the identification information may be shown in the detailed screen shown in FIG. 16. It is of note that identification information of a common friend may be shown in the detailed screen of a friend request list shown in FIG. 18, or in the detailed screen of a friend list shown in FIG. 20 or 22.

2-13. Modification 13

A request method and a friendship-establishing method are not limited to a method using local communication, a method using a multi-play function, and a method using a friend code; the methods may refer to, for example, a method in which a friend list is referred to, which list is managed by a service different from the friend registration service provided by information-processing system 1. The friend list managed by a different service is, in other words, a friend list in which identification information of friends is registered under a system (or by a service) different from friend management server 20, and more specifically, a friend list in which identification information of friends is registered on a platform different from that of friend management server 20 through execution of a program different from that of the server. The friend list may refer to, for example, a friend list of a service such as Facebook (registered trademark) or Twitter (registered trademark). In the method in which a friend list managed by a different service is referred to, game device 10 of a sender of a friend request acquires identification information of a friend of the sender, registered in the friend list, based on which identification information establishment of a friendship is requested.

2-14. Modification 14

Friend management server 20, upon detecting that two users exchange friend requests using a shared request method, may automatically register the sender and the receiver as friends, without obtaining approval of either of the friend requests. The request method refers to, specifically, a channel type. In the present modification, friend management server 20, on receiving a friend request from game device 10, determines whether a friend request has been sent to a sender of the friend request from a receiver of the friend request, by referring to friend request information DB 222; namely, friend management server 20 determines whether friend requests have been exchanged. As a result of the determination, when friend requests have been exchanged, friend management server 20 determines whether the exchanged friend requests share a channel type. As a result of the determination, when the exchanged friend requests share a channel type, friend management server 20 registers the sender and the receiver of the friend requests as friends. For example, in a case where user A has sent a friend request using a friend code to user B, and user B has sent a friend request using a friend code to user A, friend management server 20 automatically registers user A and user B as friends, without obtaining approval from user A or user B. It is of note that in a case where the channel type of both the friend requests indicates a method using a multi-play history, and games specified in the friend request are different, friend management server 20 may automatically register the sender and the receiver of the friend requests as friends. When either one of the above two determinations is negative, friend management server 20 does not automatically perform a friend registration.

2-15. Modification 15

The friend registration program stored in game device 10 or friend management server 20 may be distributed using a computer-readable non-transitory storage medium, which includes a magnetic storage medium such as a magnetic tape or a magnetic disk, an optical storage medium such as an optical disk, a magneto-optical storage medium, or a semi-conductor memory. Alternatively, the program may be distributed via a network such as the Internet.
